INTRODUCTION
In the construction of concrete slabs, either on grade, elevated, or otherwise, joints known by such terminology as expansion, contraction, etc., are purposely positioned in the slab to control where cracks in, or movement of the slab will occur. These joints may be cut into the slab after the concrete material is placed and hardened, scribed into the concrete during placement, or defined by means of various joint making materials which are placed prior to the concrete placement.

In some cases, transverse joint restraint devices, dowel bars, are cast into the slabs so that the dowel bar longitudinal center is mid point longitudinally between the joint. These devices function, primarily, to restrain vertical movement between adjacent slabs, while permitting the slab to move horizontally. Dowel bars, are typically Grade 60 (ASTM A615) plain uncoated steel or coated steel (zinc galvanized, epoxy or other coating material) of various cross sectional areas to accommodate anticipated loads. The coating for current, steel, dowel bars and dowel baskets is to prevent, or forestall corrosion, rusting, of the steel as a result of environmental or project conditions.

Dowel devices are delivered to the jobsite either as individual bars or assembled in sections known as baskets.
The FiberDowel is the answer to the aforementioned corrosion. In addition, the material composition of the device makes it an electrical and thermal insulator.
The data accompanying this introduction presents the case for the use of FiberDowel in applications where corrosion due to environmental or project conditions is a concern, or where other properties of FiberDowel lend themselves to use on a project.
